Subject: [PATCH 10/10] ARM: dts: bcm2711: Add vmmc regulator in emmc2
Date: Fri, 6 Mar 2020 11:38:55 +0100 [thread overview]
Message-ID: <20200306103857.23962-11-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200306103857.23962-1-nsaenzjulienne@suse.de>
The SD card power can be controlled trough a pin routed into the board's
external GPIO expander. Turn that into a regulator and provide it to
emmc2.
